The real question is, "What is the value of comparable properties in the area?"
If the value of comps are in the $26,000 range, then you should pay $1,000 because the appraisal price is unrealistic and $1,000 is what the net value of the house is worth today.
On the other hand, if the value of comps are in the $50,000 to $60,000 range, then the appraiser had a great eye for spotting the existing damage and priced the house accordingly. If the comps are $51,000 or more, then $26,000 is a fair market value of the property.
